Arduino Programming Remotely

Useful tool to program and control Arduino remotely using Bluetooth.

[Features]
App is used to program (change pin settings) of Arduino remotely using Bluetooth. You do not need to download programs to change pin mode. You can do it remotely using this app.

It has predefined messages (Arduino functions/commands) like pinMode, digitalWrite etc. and user only has to tap on the pin number to construct messages. It is also used to control the Arduino remotely using Bluetooth.

Its a great tool to to learn Arduino in the most fun way by chatting with Arduino. Many Arduino sketches (program code) can be developed around this app to enhance learning experience. Using this app is a good interactive way of learning machines. It is also used to quickly test Arduino and Arduino based machines.

It uses Bluetooth for communication. You will need a Arduino with Bluetooth. You can find many tutorials to connect Bluetooth like HC-05 to Arduino. You also need to upload in Arduino the sample sketch given here. This sketch can be customized/changed to suit your needs, language and enhance your experience.

Free version of App will stop after 2 minutes of usage, for unlimited usage please download 'Pro' version form Google Play.
